Hello, just updating / renaming this Github issue to "HNSW Index creation fails on Greenplum (PostgreSQL 12.12)"
Here's what I'm getting as error:
warehouse=# CREATE INDEX ON t USING hnsw (val) WITH (maxelements = 10, dims=3, m=3);
ERROR: could not map shared memory segment "/PostgreSQL.90204": Invalid argument (dsm_impl.c:327) (seg13 10.128.0.20:8001 pid=260965) (dsm_impl.c:327)
warehouse=#

Thanks for the report!
The code has changed a lot since the bug was reported (see https://neon.tech/blog/pg_embedding-on-disk-hnsw-index).
Could you please check if it's still reproducible (you can use this PR where's the compilation for Postgres 12 is fixed).
